Color: Brown系 Material: Shell Parts: Buttons These are 13mm brown shell buttons with rims. I exhibited these before, but this time I'm offering 500 pieces at a special price. Shell buttons have a better luster and a more luxurious feel than regular polyester buttons. I think they can be used for items other than clothing, such as accessories. The actual items are as shown in the photos. Please understand that shell buttons are a natural material, so there are differences in color and pattern from piece to piece. Please consider them if you like. Thank you.
